The City Carrier Cost System (CCCS) is a statistical study of mail delivered on city carrier routes. For each selected route, a data collection technician selects a sample of mail to be delivered on the scheduled test date. The technician records the mail class, product type, and other characteristics of each manually sampled mailpiece directly into a portable microcomputer using the Computerized On-Site Data Entry System (CODES) data collection software. The Postal Service conducted 9,257 and 8,694 CCCS tests in fiscal years (FY) 2019 and 2020, respectively. Our objective was to assess the reliability of CCCS data and evaluate CCCS sampling methodologies to identify opportunities for improved efficiencies.
